Frequently Asked Questions
What is Missouri’s supplemental/bonus tax rate?
Some states tax bonuses, which are also called supplemental earnings. Find Missouri’s supplemental rate in our Payroll Resources under “Withholding Requirements”.
Are bonuses taxed differently than regular pay?
Yes. Bonuses are taxed more than regular pay because they are considered supplemental income. They are always federally taxed, no matter which tax bracket you’re in.
Bonuses are taxed either by using the percentage method or the aggregate method. PaycheckCity has both percentage and aggregate bonus free calculators.
What is the percentage method for bonuses?
The percentage method is used if your bonus comes in a separate check from your regular paycheck. Your employer withholds a flat 22% (or 37% if over $1 million). This percentage method is also used for other supplemental income such as severance pay, commissions, overtime, etc. Supplemental wages are still taxed Social Security, Medicare, and FUTA taxes.
What is the aggregate method for bonuses?
The aggregate method is used if your bonus is on the same check as your regular paycheck. Your employer will withhold tax from your bonus plus your regular earnings according to your W-4 answers. Your bonus will be taxed the same as your regular pay, including income taxes, Medicare, and Social Security.
Will my bonus be taxed even if I claim exempt in my W4?
Yes, the flat 37% rate applies even if an employee claims exemption in their federal Form W-4 from federal income tax withholding.
